Synopsis
Source of validity: Traditional
Rating (out of 5): 2
Black cohosh (Actaea racemosa, formerly Cimicifuga racemosa) has a long history of traditional use in Native American and Western herbal medicine, particularly for female reproductive health concerns. Its use for menorrhagia (excessive menstrual bleeding) is rooted primarily in traditional practice rather than robust scientific evidence. Historically, black cohosh was included in herbal formulas to help "regulate" the menstrual cycle and address symptoms associated with menstruation, including heavy bleeding, cramping, and associated discomfort. Some herbalists believe that its purported estrogenic or selective estrogen receptor modulator activity may influence menstrual function, though this is not well substantiated. Modern scientific research has focused primarily on black cohosh’s effects on menopausal symptoms (such as hot flashes) rather than on menorrhagia. Clinical trials specifically addressing menorrhagia are lacking. Some animal studies and in vitro research suggest black cohosh may have mild effects on hormonal pathways, but these findings have not been translated into clear clinical recommendations for excessive menstrual bleeding. The general consensus in the scientific community is that evidence supporting its use for menorrhagia is weak. As such, while black cohosh remains a part of traditional herbal practice for menstrual issues, its efficacy and safety for this specific indication have not been validated in well-designed clinical studies.
